Photo: Shutterstock<\/p>\nA casual peace sign in a selfie has become China\u2019s latest online privacy concern after experts warned that the popular pose could expose users\u2019 fingerprints.<\/p>\n
In a mainland workplace reality show aired in April, financial expert Li Chang used a celebrity selfie to show how clearly visible fingers in a photograph could put personal biometric data at risk.<\/p>\n
Li said fingerprints could potentially be extracted from selfies taken within 1.5 metres if the fingers faced the camera directly. Even at a distance of 1.5 to 3 metres, around half of the hand details could still be recovered.<\/p>\n
The programme showed fingerprint ridges becoming visible after the image was enhanced with photo-editing software and artificial intelligence (AI) tools.<\/p>\n
According to China Newsweek, Jing Jiwu, a cryptography professor at the University of Chinese Academy of Sciences, said portrait photos taken with high-quality cameras could make it possible to reconstruct hand details from a \u201cscissor hand\u201d pose.<\/p>\n

He noted that fingerprint recovery was usually difficult due to factors such as lighting, focus and image clarity. However, the risk increases when photographs are taken with higher-resolution devices or when criminals obtain multiple related images.<\/p>\n","protected":false},"excerpt":{"rendered":"A casual peace sign in a selfie has become China\u2019s latest online privacy concern after experts warned that…\n","protected":false},"author":2,"featured_media":477170,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":"","_share_on_mastodon":"0"},"categories":[74],"tags":[291,1307,289,1423,798,208974,3901,109352,5190,435,153032,381,5214,55636,79632,2006,4737,715,208979,982,3785,2594,15168,124442,54343,40177,18,2007,208975,36962,85439,1943,208983,846,208973,208982,19418,208985,12668,23695,27127,188887,2598,4596,19,202769,208980,17,20585,62816,47086,1109,7219,208986,32877,11723,44497,12817,208978,208981,824,76346,17500,208976,172,523,32228,11986,9588,208977,14614,85595,827,2792,12368,12443,208984,50444,53051,57274,5570,864,190029,1799,753,82,1238,1817,3551,95146,128,13563,17752,124675,836,53971,52497,40351,8972],"class_list":["post-477169","post","type-post","status-publish","format-standard","has-post-thumbnail","category-technology","tag-ai","tag-apps","tag-artificial-intelligence","tag-attendance","tag-beauty","tag-biometric","tag-blur","tag-calls","tag-camera","tag-celebrity","tag-centre","tag-china","tag-chinese","tag-clarity","tag-cloning","tag-company","tag-concern","tag-crime","tag-criminals","tag-cybersecurity","tag-dark-web","tag-data","tag-devices","tag-difficult","tag-documents","tag-editing","tag-eire","tag-employee","tag-enhanced","tag-experts","tag-exposes","tag-facial","tag-filters","tag-financial","tag-fingerprints","tag-fists","tag-focus","tag-forged","tag-fraud","tag-habits","tag-hand","tag-high-quality","tag-home","tag-identity","tag-ie","tag-illegally","tag-impersonate","tag-ireland","tag-leaked","tag-lighting","tag-lock","tag-media","tag-online","tag-palm-reading","tag-peace","tag-phone","tag-photographs","tag-portrait","tag-pose","tag-posting","tag-privacy","tag-professor","tag-reality-show","tag-reconstruct","tag-research","tag-risk","tag-risks","tag-scam","tag-sciences","tag-scissor","tag-screen","tag-selfie","tag-services","tag-shanghai","tag-show","tag-sign","tag-silicone","tag-slimming","tag-smart","tag-smooth","tag-social","tag-software","tag-suspicious","tag-system","tag-tech","tag-technology","tag-television","tag-test","tag-theoretical","tag-tools","tag-tv","tag-university","tag-variety","tag-victims","tag-video","tag-visible","tag-voice","tag-warned","tag-workplace"],"share_on_mastodon":{"url":"","error":"Validation failed: Text character limit of 500 exceeded"},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/posts\/477169","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/comments?post=477169"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/posts\/477169\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/media\/477170"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/media?parent=477169"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/categories?post=477169"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/tags?post=477169"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
